CONE-CLUTCH LINING.

Specification of Letters Patent.

Patented Dec. 1916.

Application filed July 10, 1916. Serial No. 108,435.

To all whom it may concern:

Be it known that I, WILLIAM AGIITMEYER, a subject of the- German Emperor, and a resident of Middletown, in thecounty of Middlesex and State of Connecticut, have invented a new and Improved Cone-Clutch Lining, of which the following is a full,

. clear, and exact description.

The object of the invention is to provide a new and lmproved cone clutch or brake llning of a woven'fabrie material arranged to permit the use of a straight fiat piece of fabric material subsequently shrunk to the conical face of the clutch to assume the shape thereof.

In order to produce the desired result, a webbing of textile material is woven in such a manner that it is gradually denser in texture in a direction transverse to the length of the webbing so'that when this webbing is formed into an endless band and placed on a cone clutch and subjected to a shrinking solution then the webbing shrinks onto the peripheral face of thecone clutch and assumes the shape thereof. A practical embodlment of the invention 18 represented in the accompanying drawings forminga part of this specification, in

which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a face view of the lining as applied to a cone clutch, parts being shown 1n section; Fig.2 is a transverse section of the same with the lining in position prior to the shrinking operation; Fig. 3 is a similar view of the same partly in elevation with the lining shrunk on the cone pulley and fastened thereto by special fastening means; Fig. 4: is an under side view of a portion of the webbing with some of the filling removed to show the arrangement of the warp threads;

Fig. 5 is a plan view of the same; Fig. 6 is an enlarged transverse section of the same;

of the same; Fig. 8 is a diagrammatic view fof the same; and Fig. 9 is a plan view of a beltvformed from a straight piece of webbing and subjected to. shrinking action to cause the webbing to assume a segmental shape. I

The lining 10 for the conical rim 11 of a clutch 12 or other similar device is preferably formed of a Hat straight webbing preferably made of two interwoven plies or layers 13 and 14, of which the layer 13 is the under layer and is adapted to fit onto the peripheral face of the rim 11. The under layer 13 is woven in such a manner that it is gradually denser in texture in a direc tion transverse to the length of the webbing. This result may be produced in several Ways but, as shown, the layer 13 is made in three lengthwise extending portions l5, l6 and 17, of which the portion 17 has a less number of warp threads than the portion 16 and the latter has a less number of warp threads than the portion 15, the portions being prefcrab] y alike in width. Thus when the layer 13 is woven the portion 15 is denser in texture than the portion 16 and the latter is denser in texture than the portion 17. The upper layer let is of a uniform texture throughout and its warp threads are approximately the same in number to the inch as the portion 15 of the under layer 13. The two layers 13 and 14 are interwoven by the use of the binding thread 18, as indicated in Figs. 6, 7 and 8.

The webbing produced in the manner described -is cut off to a suitable length and the ends are then brought'together to abut and to be fastened together by stitches 20 (see Fig. 3) or other suitable fastening means, thus formingan endless band of an inner diameter correspomling approximately to the largest diameter of the cone-shaped rim 11. The band is placed in position on the rim 11 with the densest portion at the largest diameter of the rim (see Fig. 2) and then the clutch with the band thereon is immersed in a shrinking solution whereby the webbing is saturated and, owing to the difforence in thedensity of the texture of the shrinks more than the portion 15 and less than the portion 17. Thus the shrinking of the band causes a snug fitting of the band on the peripheral face of the rim 11. The outer layer 14, owing to the fact'that it is bound by the threads 18 to the layer 13, shrinks with the inner portion and thus assumes with the latter a conical: shape. It is understood that the outer layer of the webbing is. preferably of uniform texture; as it is the wearing surface, so that a ,unlform wear is insured.

The shrinking solution is used when hot I and is preferably of an oily nature capable ofsaturating the textile material to shrink the same as above described. The shrinking solution impregnates the webbing and makes ,it more compact, and the solution increases the wearing quality of the lining and insures? an easy and smooth running of the clutch when the latter is in use.

In order to hold the lining 10 against displacement on the rim 11 use is ade of fastening means such as studs se in the rim 11 and provided with prongs 31 projecting'beyond the conical peripheryof the rim to be embedded in the lining '10 by the use of a suitable-pressure device for spreading the prongs 31 at a point approximately I in texture in a direction transverse to the intermediate the two layers 13. and lt so that the prongs do not project beyond the peripheral face of the lining (see Fig. 3). The particular fastening device, described forms the subject matter of a separate application filed under even date herewith.

Although I have shown and described-the webbing for use as a liningfor cone clutches, it is evident I do not limit myself to this particular use, as ladies" belts 40 of seg mental shape, such as shownjn Fig. 9for instance, can be made from a piece of flat straight webbing having .a varying density length of the webbing and shrunk on'a conical surface inthe same'm'anner as above dc;- scribed relatiyely to the lining.
